WASTEWATER MANAGEMENT

Sewerage and Storm Water Networks 

Hydromanagement’s personnel have extensive experience in studies related to sewerage and storm water networks. Dynamic calculation of sewer networks is conducted with the use of relevant software packages, which simulate sewage and rainwater runoff, as well as pollutant loads’ transportation through the sewerage network to natural recipients. Their expertise extends to vacuum drainage systems. Examples are shown below:

  • Wastewater collection network in the Olympiada settlement – vacuum sewer system consisting of 30 km  piping network, 550 collection chambers –vacuum valves and 2 vacuum pumping stations – 6.500 EP
  • Vacuum sewage networks of Galatades and Kariotissa settlements – Vacuum system consisting of 16.7km piping network, 328 collection chambers – vacuum valves, 2 vacuum pumping stations, 4.500 EP
  • Vacuum sewage networks and wastewater treatment plant in Stratoni, Municipality of Aristotelis - Vacuum system consisting of 2.4 km piping network, 41 collection chambers – vacuum valves and vacuum pumping station. MBR treatment method
  • Design of internal sewerage networks for the Municipalities of Methoni, Makrigialou, N. Agathoupoli and Old Palaiochoriou EP 15.000 –gravity pipes of 57.000m – 11 pumping stations

HYDROMANAGEMENT has carried out a substantial number of specialized projects in the field of highway drainage. During the construction of Egnatia Highway by Egnatia Odos S.A., Hydromanagement undertook several projects concerning the sewerage and drainage design of over 70.000m of road and over 50.000m of drainage pipes in different areas, interchanges, connections and tunnels sections of the highway.
